Well, adding

  'Encode.pm' => 'sub',

to %Preload will pack ALL of them for a whopping 21 MB of stuff for anyone
who just wants to

  use Encode qw(encode decode);
  ...
  $string = decode("utf8", $bytes);

So I'm hesitant to do that. If someone knows in advance which encodings they need
they can add an appropriate -M option to their pp command. If they want to be 
flexible (e.g. program takes the encoding as input), this could get cumbersome, though.

There was once a suggestion on the list to add an option to pp that would mean
"include Foo.pm and everything below Foo/". Implementation would be almost trivial
(just call _glob_in_inc("Foo.pm")), the problem is to come up with a good name
for this option.
